I am writing a query in mysql i am not familer with the recursive query to much.
how and what i need to do to optimization of the below query as the conditions i put not looks good ,there must be a easier way to do same.
select
b.entity_id
from
entity_hierarchies a,
entity_hierarchies b
where
a.entity_id = 25
and a.entity_type = 'user'
and b.entity_type = 'idea'
and a.Geography_Geography =
case
when
a.Geography_Geography is null
then
a.Geography_Geography
else
b.Geography_Geography
end
and COALESCE(a.Geography_Country, '') =
case
when
a.Geography_Country is null
then
COALESCE(a.Geography_Country, '')
else
b.Geography_Country
end
and COALESCE(a.Geography_DistrictOrCounty, '') =
case
when
a.Geography_DistrictOrCounty is null
then
COALESCE(a.Geography_DistrictOrCounty, '')
else
b.Geography_DistrictOrCounty
end
and COALESCE(a.Geography_State, '') =
case
when
a.Geography_State is null
then
COALESCE(a.Geography_State, '')
else
b.Geography_State
end
and COALESCE(a.Geography_City, '') =
case
when
a.Geography_City is null
then
COALESCE(a.Geography_City, '')
else
b.Geography_City
end
Intro
I noticed you could rewrite some of these statements in a much simpler form.
So for example:
and a.Geography_Geography =
case
when
a.Geography_Geography is null
then
a.Geography_Geography
else
b.Geography_Geography
end
can simply become:
AND ( a.Geography_Geography is null or a.Geography_Geography = b.Geography_Geography )
Final Solution
select
b.entity_id
from
entity_hierarchies a,
entity_hierarchies b
where
a.entity_id = 25
and a.entity_type = 'user'
and b.entity_type = 'idea'
AND ( a.Geography_Geography is null OR a.Geography_Geography = b.Geography_Geography )
AND ( a.Geography_Country is null OR a.Geography_Geography = b.Geography_Country )
AND ( a.Geography_DistrictOrCounty is null OR a.Geography_DistrictOrCounty = b.Geography_DistrictOrCounty )
AND ( a.Geography_State is null OR a.Geography_State = b.Geography_State )
AND ( a.Geography_City is null OR a.Geography_City = b.Geography_City );

I am trying to write a MySql statement with a conditional where clause.
something like this:
set #price = 5000 ;
set #city = 1324368075;
select count(*)
from property
where case when #price is not null then
price < #price
end
and (case when #city is not null then
CityId = #city
end)
the variable should be included in the query only if it is not null.
My attempts have failed so far. Any ideas?
Edited:
Sorry I spoke too soon ysth,
these two queries are supposed to yield the same count but they dont.
Edit #2: Execution plan & indexes
Here's the query:
set #CountryId = null ;
set #CityId = 1324368075 ;
set #StateProvince = null ;
set #CategoryId = null ;
set #TransactionTypeId = null;
set #Price = 5000;
SELECT
Count(*)
FROM
meerkat.property
WHERE
(CASE WHEN #CountryId IS NOT NULL THEN CountryId = #CountryId ELSE 1 END)
AND (CASE WHEN #CityId IS NOT NULL THEN CityId = #CityId ELSE 1 END)
AND (CASE WHEN #CategoryId IS NOT NULL THEN CategoryId = #CategoryId ELSE 1 END)
AND (CASE WHEN #StateProvince IS NOT NULL THEN StateProvince = #StateProvince ELSE 1 END)
AND (CASE WHEN #TransactionTypeId IS NOT NULL THEN TransactionTypeId = #TransactionTypeId ELSE 1 END)
AND (CASE WHEN #Price IS NOT NULL THEN Price <= #Price ELSE 1 END)
AND IsPublic = 1
AND IsBlocked = 0;
Thanks in advance
If no when conditions are met, case returns null. If you want each test to pass, you need to return a true value instead, so:
case when #price is not null then
price < #price
else 1 end
and ...
I have in my table one row with a char value. When the value is NULL then a false should be outputted. If the value is not NULL then a true should be outputted.
So when I try to set user_group.tUser to 0 or 1 then I'm getting this error:
Invalid column name 'false'.
Invalid column name 'true'.
SELECT COALESCE((SELECT name
FROM v_company
WHERE companyId = userView.companyId), ' ') AS company,
userView.value AS companyUser,
userView.display AS displayedUser,
CASE
WHEN user_group.tUser IS NULL THEN 0
ELSE 1
END AS userIsMemberOfGroup
FROM v_user userView
LEFT OUTER JOIN cr_user_group user_group
ON ( user_group.group = 'Administrators'
AND user_group.tUser = userView.value )
ORDER BY company ASC,
displayedUser ASC
I think this is the logic you want:
SELECT COALESCE(v.name, ' ') as company,
u.value as companyUser, u.display as displayedUser,
(EXISTS (SELECT 1
FROM cr_user_group ug
WHERE ug.group = 'Administrators' AND
ug.tUser = uv.value
)
) as userIsMemberOfGroup
FROM v_user u LEFT JOIN
v_company c
ON c.companyId = v.companyId
ORDER BY company ASC, displayedUser ASC ;
In general, MySQL is very flexible about going between booleans and numbers, with 0 for false and 1 for true.
You can use MySQL IF function to return 'false' when name IS NULL, else 'true':
SELECT IF(name IS NULL, 'false', 'true')
FROM table;
A simple CASE expression would work here:
SELECT
name,
CASE WHEN name IS NOT NULL THEN true ELSE false END AS name_out
FROM yourTable;
We could also shorten the above a bit using IF:
IF(name IS NOT NULL, true, false)
SELECT
CASE
WHEN name IS NULL THEN 'false'
ELSE 'true'
END
FROM
table1;
I have a query which is taking too long to execute.
I used database tuning advisor to check this query and it suggested some missing indexes and statistics. The problem is I can't create missing index and statistics on those tables because it will slowdown insert/update and affect other scripts. They can't sacrifice their scripts performance because of my query.
Without the help of DTA or disturbing other scripts how do I have to tune my query? Can i break it into small pieces? If so, how?

Try to remove functions called in the query like : Exrate() and Getaveragefxrate().
Also change the case statement, where you are using subquery as following.
In the end of the query, use
left outer join trf.lineitemfundbdescription lifd
on lll.orgid = lifd.orgid and lll.lineitemid = lifd.lineitemid
and then the case will be changed to
case
when lifd.orgid is null then lll.lineitemname
else lifd.lineitemshortdescription End As LineItemName
It will fine tune your query to a level and gives you a correct execution plan and advice accordingly.
Remember that execution plan does not show the plan of user defined functions called with in the query.
I have created this query:
Where
(companies.col_335 <> NULL) And
(companies.col_285 = '') Or
(companies.col_346 <> 'Yes') Or
(companies1.col_275 = '') Or
(companies1.col_294 <> 'Yes')
I want the selection to only include records where the FIRST comparision above is true, and at least one of the other 5 comparisions are true.
Is this the right way of doing this?
No. AND has higher precedence over OR (basic boolean logic). Use parentheses to do it right:
Where
(companies.col_335 <> NULL) And
((companies.col_285 = '') Or
(companies.col_346 <> 'Yes') Or
(companies1.col_275 = '') Or
(companies1.col_294 <> 'Yes'))
You are missing some brackets:
Where
(companies.col_335 <> NULL) And
(companies.col_285 = '' Or
companies.col_346 <> 'Yes' Or
companies1.col_275 = '' Or
companies1.col_294 <> 'Yes')
What you were trying to do would do the AND FIRST and then do OR with any of the last 3. i e:
(companies.col_335 <> NULL And companies.col_285 = '')
Or
companies.col_346 <> 'Yes'
Or
companies1.col_275 = ''
Or
companies1.col_294 <> 'Yes'
You're almost there... you should surround at paranthesis the or section.
WHERE
(companies.col_335 <> NULL)
AND
(
(companies.col_285 = '') Or
(companies.col_346 <> 'Yes') Or
(companies1.col_275 = '') Or
(companies1.col_294 <> 'Yes')
)
I am trying to combine these 2 queries in such a way to determine who the PI is that owns equipment (>$100K value). I have the ability to find all the equipment one PI owns that is greater then 100k. I also have the ability to see all the PIs. I just cannot get these 2 queries to combine. I have tried with a WHERE subquery and an EXIST subquery. I want to be able to find all the equipment (matched with its PI owner) where the PI exists in query #2.

Perhaps you're looking for the IN keyword in your WHERE clause?
